The study is an attempt to measure psychopathic tendencies in the girl who becomes pregnant out of wedlock compared with the average non-pregnant college co-ed. This characteristic, when evidenced in a subject's personality, may be reflected in a High T score on the Pd scale of the 1MPI.

The problem with which this investigation was concerned was to determine whether or not fear of death was related to positive future time perspective and self-esteem.

The problem of this research may be stated as a study of the relationship between successful weight reduction on the part of people involved in a group program, and the two variables of ego strength and social participation.

The purposes of the present study are to try to establish whether perception and motor skill are determinant factors of performance on the Bender-Gestalt Test and to investigate the degree of relationship and importance of each factor on the B-G-T.

The purpose of this study is to investigate, empirically, the response of the severely mentally retarded to different types of music, tonic and sedative, as well as responses during "quiet" periods.

The purpose of the present study was to further investigate the effects of frustration on the reward value of a goal object. Under the assumption that animals will learn to take the shortest path to a goal and that the reward value of an object will increase as effort increases, the following hypothesis was proposed: If rats are frustrated in the short path of a single choice maze (experimental group) then the experimental group's running time for the long path will be less than that of a control group not frustrated in the short path.

The problem of this study was to determine the relationship between the nature of an individual's self-concept and belief system to his orientation toward internal versus external control of reinforcement. This study was designed to investigate the relationship of two variables, self-concept and open versus closed belief system, to a third variable, locus of control.

Since much of the existing research which points to the low validity of the Draw-a-Person technique has used differentiation of diagnostic categories as a criterion, this study will be restricted to a consideration of the Draw-a-Person technique as a means for discriminating between a group of individuals who manifest conflicts in the area of sexual adjustment and a control group which does not show these conflicts in any appreciable amount.

The present study is an attempt to determine which of several different types of reinforcers is most effective in discrimination learning using institutionalized mentally retarded boys of different intellectual levels as subjects. If one type of reinforcement works more effectively in conditioning one level of institutionalized mentally retarded subject, then that type of reinforcement could be used to greater advantage in controlling behavior than some other, less effective kind of reinforcer.

It has not yet been demonstrated that music can be used therapeutically with profoundly retarded children. One way these children might be helped to respond to music, and therapeutically benefit from it, would be to use operant conditioning in an effort to enhance gross motor activity and then progressively shape responses until more complex behavior patterns are formed. Once these children can respond motorically in the presence of musical stimuli, continuation of responding may be possible by pairing motor activity with musical stimuli. This experiment investigated the effects of operant conditioning and music on the motor activity of profoundly retarded children in an effort to determine the therapeutic usefulness of music with such children.

The problem of this thesis is the question of whether appreciation of humor is characteristic of adult creatives. Also, can the humor factor be a significant factor in the prediction of creative individuals? As a consequence of the theory and experimental evidence associated with the relationship between humor and creativity, the following hypothesis is formulated for further study: there is a significantly positive relationship between humor appreciation and creative ability.

It was the purpose of this investigation to add to the scientific knowledge of death and suicide and to present an exploratory investigation into the possibility of developing an attitudinal technique or scale of measuring responsiveness toward death, which has to do with how a person responds to his own death and the "death-instincts."

The exact properties of the interaction between emotional drives and other psychological phenomena is still a vastly unexplored field. The purpose of this paper will be to examine further the effects of one of these emotional drives, that of fear, on task performance, and to explore some of the theoretical conceptualizations already put forth regarding this interaction.

This thesis proposes three hypotheses: first, that persons with a high generalized expectancy for internal control of reinforcement will react to many of life's situations in a problem-solving or need-persistent way; second, that those persons high in the belief of external control will be more extra-punitive in their reactions to frustrating situations; third, that persons with a high belief in internal control of reinforcement are more ready to learn in chance situations.

The design of this experiment was developed to investigate the presence of success-striving and failure-avoidant motivational patterns in the level of aspiration behavior of retarded subjects. The primary objective of this study is to show that success-strivers are present in mentally retarded groups, even if in the minority.
